About the Team
We are looking for a talented DevOps Engineer with a focus on Cloud/Platform engineering to join our Technology Department in Lisbon.
As a DevOps/Cloud Platform Engineer, you'll build and evolve the infrastructure platform that powers our engineering teams across multiple cloud providers. You'll own the automation, networking, Kubernetes platforms, and shared services that enable secure, scalable, and reliable application delivery.
Fluency in English is essential for this role. Please ensure your CV is submitted in English as part of your application.
What you'll do
- Build Multi-Cloud Platforms: Design, provision, and operate infrastructure across AWS, Oracle Cloud Infrastructure (OCI), StackIT, and OpenStack using Infrastructure as Code.
- Manage Kubernetes Platforms: Operate and evolve managed Kubernetes environments, including Amazon EKS and Oracle OKE, ensuring scalability, security, and operational excellence.
- Platform Automation: Develop reusable infrastructure abstractions using Terraform, Terragrunt, Terramate, and Crossplane (XRDs/Compositions) to enable self-service infrastructure for engineering teams.
- Operate Cloud Services: Deploy and maintain managed cloud services such as Amazon RDS, object storage, networking services, and cloud-native integrations.
- Own Platform Services: Build and operate shared platform components including Kafka, HashiCorp Vault, Kubernetes Operators, ingress controllers, and other foundational services.
- Cloud Networking: Design and maintain secure cloud networking across multiple environments, including VPCs/VNets, routing, peering, load balancers, firewalls, and Layer 4/Layer 7 traffic management.
- Service Mesh & Connectivity: Design and operate service mesh technologies (e.g., Istio) to provide secure service-to-service communication, observability, and traffic management.
- Identity & Access Management: Implement and maintain identity and access solutions using Keycloak, cloud IAM services, and API gateways to provide secure authentication and authorization.
- Platform Security: Embed security into the platform through policy enforcement, least-privilege access, secrets management, and policy-as-code.
